This is a note to let you know that I've just added the patch titled ACPI/PCI: pci_link: Include PIRQ_PENALTY_PCI_USING for ISA IRQs to the 4.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: acpi-pci-pci_link-include-pirq_penalty_pci_using-for-isa-irqs.patch and it can be found in the queue-4.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 98756f5319c64c883caa910dce702d9edefe7810 Mon Sep 17 00:00:00 2001 From: Sinan Kaya <okaya@xxxxxxxxxxxxxx> Date: Mon, 24 Oct 2016 00:31:32 -0400 Subject: ACPI/PCI: pci_link: Include PIRQ_PENALTY_PCI_USING for ISA IRQs From: Sinan Kaya <okaya@xxxxxxxxxxxxxx> commit 98756f5319c64c883caa910dce702d9edefe7810 upstream. Commit 103544d86976 ("ACPI,PCI,IRQ: reduce resource requirements") replaced the addition of PIRQ_PENALTY_PCI_USING in acpi_pci_link_allocate() with an addition in acpi_irq_pci_sharing_penalty(), but f7eca374f000 ("ACPI,PCI,IRQ: separate ISA penalty calculation") removed the use of acpi_irq_pci_sharing_penalty() for ISA IRQs. Therefore, PIRQ_PENALTY_PCI_USING is missing from ISA IRQs used by interrupt links. Include that penalty by adding it in the acpi_pci_link_allocate() path.
